Which type of telescope would perform better on a mountaintop than at a lower elevation?

Chemistry
1 answer:
marishachu [46]3 years ago
5 0

when an optical telescope located on the ground is used to view the sky the image has to surpass through the earth's atmosphere which is polluted. so the resolution wont be clear. When viewed on a mountain top both optical and infrared telescopes would perform better as the air above the atmosphere is less depth and cleaner.

Calculate the number of particles in 8grams of oxygen molecule
lana [24]
Moles of oxygen = mass/molar mass of O2 = 8/31.998 = 0.25 moles.

Number of particles = moles x 6.02 x 10^23 = 0.25 x 6.02 x 10^23 = 1.505 x 10^23 particles.

Hope this helps!

Question 2 (2 points)
poizon [28]

Answer:

m_w=439.2g

Explanation:

Hello!

In this case, since the by-mass percent of a solution is a measure of the mass of the solute over the mass of the solution:

\%m/m=\frac{m_{solute}}{m_{solution}} *100\%

As we know the mass of the solution and the by-mass percent, we can compute the mass of glucose in the 480 g of solution:

m_{solute}=\frac{\%m/m*m_{solution}}{100\%}

Thus, by plugging in the data, we obtain:

m_{solute}=\frac{8.5\%*480g}{100\%}=40.8g

Finally, since the solution is made up of glucose and water, we compute the mass of water as follows:

m_w=m_{sol}-m_{solute}=480g-40.8g\\\\m_w=439.2g

Best regards!

What is the process of separating liquids by boiling points?
Alona [7]

Answer:

Fractional distillation (often shortened in high school to just distillation)

Explanation:

Some elements have different boiling points and can be separated by boiling one element out and condensing it. This is how sodium acetate is made, for example.

Hope this helped!
